Table 5–4 (Cont.) Environment Variables Set During System Conﬁguration

Variable Attributes Function

console NV Sets the device on which power-up output is displayed.

GRAPHICS—Sets the power-up output to be

displayed at a graphics terminal or device

connected to the VGA module at the rear of the

system.

SERIAL—Sets the power-up output to be displayed

on the device that is connected to the COM1 port

at the rear of the system.

ew*0_mode NV Sets the Ethernet controller to the default Ethernet

device type.

‘‘aui’’—Sets the default Ethernet device to AUI.

‘‘twisted’’—Sets the default Ethernet device to

10BASE-T (twisted-pair).

‘‘auto’’—Reads the device connected to the Ethernet

port and sets the default to the appropriate

Ethernet device type. (This option is not

implemented at product introduction.)

er*0_protocols,

ew*0_protocols

NV Determines which network protocols are enabled for

booting and other functions.

‘‘mop’’—Sets the network protocol to mop: the

setting typically used for systems using the

OpenVMS operating system.

‘‘bootp’’—Sets the network protocol to bootp: the

setting typically used for systems using the DEC

OSF/1 operating system.

‘‘bootp,mop’’—When the settings are used in a list,

the mop protocol is attempted ﬁrst, followed by

bootp.

Key to variable attributes:

NV —- Nonvolatile. The last value saved by system software or set by console commands is

preserved across system initializations, cold bootstraps, and long power outages.

W —- Warm nonvolatile. The last value set by system software is preserved across warm bootstraps

and restarts.
